Paragraph: A smooth and vertical circular wire frame of radius 2 m is fixed inside water as shown. A small bead of specific gravity 0.5 is threaded on the wire and is kept at the origin. If the bead is imparted velocity v ₀ towards positive x axis, it moves on the wire frame then neglecting effect of viscosity Question: If bead is given minimum velocity V ₀ at origin as calculated in first question then acceleration

Options

  1. A5 ~g
  2. Bg a 2 ~g
  3. C2 ~g a 3 ~g
  4. D3 ~g a 4 ~g

Correct answer

D. 3 ~g a 4 ~g

Step-by-step solution

Inside water a _ t = g as it moves up, with time t , decreases a_t increases i.e. speed increases and rate of increase of speed (a_t ) also increases
